Wisconsin Corn Growers Association

The Wisconsin Corn Growers Association is a membership organization that represents the interest of state corn growers in the growth and management of corn grown for on-farm feeding and commercial sale. WCGA works with other organizations in areas of mutual concern, and brings together corn growers to provide information and education at regional corn conferences and the annual Wisconsin Corn•Soy EXPO. The WCGA is a partner with the National Corn Growers Association to represent corn grower interests nationally and internationally.

The program is regulated by the Wisconsin Department of Agriculture Trade and Consumer Protection and governed by the Wisconsin Corn Promotion Board. Directors on this board are corn growers elected by their fellow growers.
